TO ALL WHOM IT yMAY CONCERN:

Be it known that I, SAMUEL W. ADAMS, of Providence, in the county ofVA Providence, and AState of Rhode Island, have invented certain new and useful Improvements in Machinery for Making Eyelets; and I do hereby declare that the following is a full, clear, and exact description of the same, 'reference being had to the accompartying drawings, making part of this specification, in which- Figure 1 is a plan of the improved machine, complete.

Figure 2 is a side elevation of the feeding mechanism detached.

Figure 3 is a sectional view of the compound male-cutter and former, and the spindle K that carries the same.

Figure 4 is a side view of the clipping mechanism hereinafter mentioned, detached from the machine.

Figure 5 is a plan of the parts which carry the compound male cutter and former; the female cutter and forming-die and its clearing punch, together with the mechanism which operates the same.

Figure is a plan of the parts which carry the compound male-cutter and former and the clearertso called) for clearing 'the formed eyelet from the punch, together with the mechanism which operates the same.

Figure 'l' is a side longitudinal view of the said clearer and its operating mechanism, detached and Figure 8 is a front or end view of the said compound male-cutter and former; and the clearer, showing the application of the clearer to the purpose intended.

I Similar letters refer to corresponding parts in all the figures.

In the drawings, G is the-bed or framework of the machine, of cast iron, formed with two stands G2 for the bearingsof the main shaft A, two other stands G3 for the bearings of the sliding sleeve I, and a stand or knee, G4, for holding the compound cutter anddie. The-material of this bed is of considerable thickness, and it is constructed in the form shown and described to insure the greater stiffness and consequent precision of opera,- tion in the working parts. On the shaft A, between its bearings, are secured the cams which operate the mechanism for the performance ofthe several functions of the machine. The sliding'sleevc I is screwed into a. cross-head, N, which is connected to the cams B B bythe connections E E on each side. The -sliding spindle K, within the said. sleeve, is screwed into the cross-head1), and connected to the cam d' by the connection M. The

compound male-cutter 3, and former2, and central punch 1,'are constructed as Vshown in fig. 3. The shankf of the-cutter is fitted into the end of the sleeve I, from which it derives its motion. The former 2 is surrounded by a spiral-spring, S, which exerts a force between the shoulder on the former at c and the shoulder at e, on the interior of the cutter 3, to draw the former into the cutter as withinv a sheath, until the functions to which it is subordinate are performed. A hollow set-screw, n, isscrewed into the cavity in the end of the cutteris 'shank by means of which the protrusionf-of the former 2 is regulated and controlled. Within the former 2 slides the central punch 1, the shank q of which is formed with a shoulder at r, againstjwhich the end of the former 2 bears, and from which it derives its motion. The end of this shank g is fitted in the end of the sliding spindle K, by which it is operated; and the parts being ,thus constructed and arranged, it will be seen that when the central punch `1 is drawn into the former 2, the spring S will press the end of the former against the'` end of thc set-screw n, which, being set at the proper point, will permit the former 2 to withdraw itselfinto the cu'tter 3, so 'that its forming end will be flush or even with the face of the cutter 3, so that'in'the formation of an eyelet,

the external cutter 3 first advances and cuts from the'stock a planchet or disk; the central punch I then pro=` 'trudes from the cutter and carries the planchet into the cavity of the forming-die 5, figs. 1 and 5, to form a cup,

and when the cup and the punch have advanced sufficiently into the die to ill the same, the continued movement of the punch ,has a tendency to draw out or elongate the cup until the metal yields to the force of the punch and the top of the cup is cut out; *simultaneously with wh'iclrthe former 2 is made to protrude from the cutter in the mann-er above mentioned, and turns over the llanch on the end ofthe, cup, and completes` the eyelet. The immediate parts for forming an' eyelet thus far described do not diifer essentially in their character or purpose respectively fromA the compound moving' instruments and stationary' instruments, (so designated,) for forming an eyelet, set forth and described in Letters Patent ofthe United States No'. 44,555, granted to Jesse F. Richards, Oct. 4, A. D. 1864, to which reference is to be had.V But by means of the improved construei tion and mode of operating'the said instruments, as described, greater perfection in the formation of the eyelet is obtained in respect to the smoothness ofthe edge from which the-top ofthe cup is punched, and its capacity to stretch without splitting open when used; and the said improvement is therefore herein claimed. The stock .is supplied to the machine in-:the form of a thin met-al styipor ribbon, k, (represented inred lines,) which, for the sakeof convenience, isl wound upon a reel,C, on one side Df the machine, whence it is drawn atintcrvals by the feeding mechanism, and, after it is operated upon to form the eyelets, the residue is wound upon a. similar reel, C1, on the opposite side of-the machine, as shown in fig, 1, the reel Cl being revolved by means of a weight unwinding a cord from a drum on said reel or other suitable contrivancc to take up the perforated metal strip as it is delivered from the machine; The feeding mechanism which supplies the stock to the instruments for forming the eyelets is representcdin fig. 2, and consists of a pair of sliding clamping-jaws oZ, on thebloek F,-

between which-the metal strip passes, and is clamped and carried forward at the proper time to be operated upon by means of the lever H, pivotcd at L, and operated by the cam P on the main shaft. This cam is of a form to impart vtwo movcments'through the medium of the lever H to the mechanism, one motion being produced by an enlargement on its cylindrical surface which depresses thc'opposite end'of the lever H and the arm a: vof the movablcjaw all, which swing-s at a, and by the depression mentioned is inadeto clamp and confine the metal strip 7c between the two jaws; and the other motion being produced by the side face of` the said cam, against' which the stud 8, on thelcvcrs end, is pressed by the force Vof the spring Z, and swings the lever on its pivot",

and causes thc opposite end to slide the clamping-jaws and advance the metal confined therein to the eyelets; forming' instruments above mentioned. The metal strip is released preparatory to repeating the advancing movement by means of aA rubber washer, Y, beneath the arm X, which lifts the arm when the depressive force of the cam is removed. The sliding movement of the clamping-jaws is adjusted by means of the thumb-screw 7,- to advance the metal strip the requisite distance each time to form the successive eyelets. In the useot a metal strip of sutiicient width to cutout more than one row of planehets, a considerable saving of stock, say about one-sixth part, may be made by punching a second row midway ,between and to one side of the first punching. But in order to dottliis it is necessary rst to trimoff so much of the width of the strip as will permit the cutter tol penetrate the strip at. the proper distance from the edge thereof. This may be accomplished by trimming oii the requisite width of1 thc perforated portion by means' of shears or othernrell-known means, after the strip comes from thc machine. Butit may be performed with ,greater accuracy and precision during the passage of the strip throughthe machine, by means of thchclipping .mechanism represented in fig. 4, consisting of a shearing-chisel, p, attached tonnd moving with the cross-head N of tho sleeve I, and a' corresponding shear-ing edge, s, fixed in the stand Gi, between which the metal strip passes after being perforated, and/is clipped at the proper distarice from-thc edge, (as shown in red lincs,) the refuse portion so clipped 'off being permitted to fall at randombesidc the machine,l while the remaining portion is wound upon the take-up reel C, which, when iilled, is shifted to the position of r thc other reel C', for the stock to be again drawn therefrom in punching a subsequent row of planchets, as before described. By this means the machine is kept constantly at work, and no time lis lost in clipping the stock by an independent mechanism and afterwards ceiling the same onl the reel `to be fed properly tothe machine. After the cyelet is completely'formed, it is withdrawn fromtbe die (in-fthe end of'. the punch 1, to which it adheres, and is stripped' oif by the withdrawal of the punch into the former. 2, in the manner above explained, and it drops into a receptacle beneath the machine. It willhowever, sometimes happen either that thc eyelet will remain in the cavity of the die,`or that it will adhere to the end of the punch, and if it is not removed by some special means, owing to the nature of the eyeletfforming instruments, will -be' the means of breaking or `injuring the machine. To avoidthe first-mentioned casualty with reference to the forming-die, I arrange at the rear of the die, as shown in iig. v5, a. clearing-punch, V', which is `thrust through the die from the rear after each eyelet is completed, and the punch 1 is withdrawn by meanscfthe lever and 'rod R operated by the cam 12, on the main shaftfwherebyvthe eyelet remaini-ng in the die is surely removed before the operation of forming another eyelet in the die is commenced. The other casualty, which results from the eyelet sticking to the end yof thepunch, is `avoided by means of the mechanism shown in figs. (i, 7, and 8, consisting of a delicate finger or clearer, t, that has a movement across the axis of the punch 1, directly in front of the same, as indicated by the arrow, after the punch isdrawn into the cutter, as described, in such a manner as to strike off the adhering eyelet from the punch. The clearer t, for this purpose, swings on the pivot u, by motion imparted tb the lever W by the Vcam X on the' main shaft and the action of the spring g, saidv spring carrying the clearer to the position shown in fig. 8, above the punch, and the positive movement of the-earn X carrying the clearer across the axis of the punch in the direction indicated by the arrow, to strike off the cyelet in the manner shown and described.

Having thus described my invention, I wish it understood that I do not claim the compound moving and stationary instruments, by means of which the eyelet is formed from a metal strip, as described, the siamehavng been previously patented by Jesse F. Richards, as above mentioned, and my said invention comprising only. the

improved construction of the said moving instruments as herein described, and the improved appliances described for aiding to carry into effect the general principleor mode of operation of the machine.

What Iclaim, and desire to secure byLettcrs Patent, is

l. The' improved mode of constructing and operating the compound male-cutter l3, former 2, `and punch 1, as described, for the purpose specified. p

2. I claim a pair of reels, C C", for holding and delivering and for taking up thel metal strip, in .combination with the eyelet-forming instruments forforming eyelets therefrom, substantially as described.

I claim a pair of sliding clampingjaws, constructed and operating as described, in combination with suitable instruments for forming eyelets from a metal strip, as described, for'the purpose speciicd.

4. I'claim, in combination with the eyelet-forming instruments, constructed substantially as described, a,

clipping or trimming mechanism for trimming oft' the'perforated portion of the stock aus it passes through the machine, substantially s described.

5. I claim the clearing-punch V; in combination with the compound female-cutter and forming-die, substnntially as described, for the purpose specified. Y v

6. I claim the clearer t, substantially as described, for the purpose specified. In testimony whereof I have hereunto set my hand this third day of November, A. D. 1865.
